CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to and claims priority to Provisional Application No. 61/877,991, entitled Lounge Assembly, and filed Sep. 13, 2013. The disclosure of Provisional Application No. 61/877,991 is expressly incorporated in its entirety by reference herein.

FIELD OF THE INVENTION

This invention relates to a lounge assembly with a movable backrest allowing multiple seating configurations. In an embodiment, the seat is a lounge assembly for a boat.

BACKGROUND

In the boating industry it is desirable to provide multiple seating arrangements, typically as lounges, for passengers on boats to allow such passengers to select a particular view. For example, some passengers may want to face aft to view water activities such as skiing from the boat. Other passengers may want to face forward to view, for example, children in a bow portion of the boat. Still further it may also be desirable to provide a seat arrangement capable of accommodating multiple passengers.

In a boating environment it is important that seating arrangements be easily converted from one position to the next with little occupying of additional space or use of complex mechanisms. Unfortunately, most adjustable seating arrangements involve complex mechanisms, are difficult to operate, and/or are space consuming. For example, often heavy seats must be lifted and moved. Further, many existing adjustment mechanisms involve hinges that can present safety hazards to fingers during adjustment. Such hazards are particularly undesirable when boats are in motion or when small children are present.

Examples of patents for seating arrangements having adjustable backrests exemplifying some of the disadvantages of the prior art are: U.S. Pat. No. 7,775, 599; U.S. Pat. Nos. 6,715,825; 7,644,892; U.S. Pat. No. 6,082,805; and U.S. Pat. No. 6,651,274.

In accordance with the inventions described herein, an easily configurable lounge assembly with a movable backrest is provided with a simple to use adjustment mechanism allowing multiple seating configurations, for example, for use on a boat.

BRIEF SUMMARY

In accordance with an embodiment of the invention, a lounge assembly has a stationary base and a movable backrest to achieve multiple seating positions. This embodiment of the lounge assembly allows a center position for the backrest to provide back to back seating for two people, one facing forward and the other facing aft. The backrest is also slidable and can be locked in extreme forward or aft positions to provide a lounging configuration for passengers in a forward or aft facing position as well as in the center position for two people sitting back to back. The backrest is also tiltable from an upright configuration to a reclining position through adjustable backrest detents in a structural support for the backrest.

The lounge assembly can be made of different dimensions. For example, a seating surface thereof can be made sufficiently long so that when the backrest is at either the aft position or forward-most position, the assembly can function as a lounge, as described above. In a shorter configuration, the assembly could function alternatively as seating for two people when the backrest is centered or for a single adult when the backrest is at either the aft or forward-most positions.

An internal rail system in the seat base of the depicted embodiment is provided to allow the backrest to slide forward and backward. A locking mechanism is used to releasably lock the backrest in a desired position.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

FIG. 1 shows in perspective view a lounge assembly 11, which includes a seating surface 14 along which a backrest 13, shown in a center upright position, can be moved according to an embodiment of the invention. The backrest 13 of this embodiment is supported by two relatively thin plate supports 15 (not shown in FIGS. 1-6) extending upward from a base of the lounge assembly 11 described and shown hereafter with reference to FIGS. 7, 8, 10, 11, and 13. The design of the supports has been selected for cosmetic purposes and it will be obvious to persons skilled in the art that supports of varying design and thickness can be utilized.

The seating surface 14 has a central cushioned section as shown in FIGS. 1-6. The plate supports penetrate into the lounge base 12, through the seating surface 14, through seating surface slots 21 running the length of the seat surface 14 at the outermost two central cushioned portions of the seating surface 14. The pleats in this depicted embodiment are decorative in nature and allow for the slots 21 for plate supports 15 (FIGS. 7, 8, 10, 11, 13) to not be as visible as compared to a non-pleated surface. The plate supports 15 penetrate into the lounge base 12 and are connected to a carriage assembly 19 (not shown in FIGS. 1-6) within the lounge base 12.

A handle 17 connected to a carriage assembly (which includes a locking mechanism) is shown projecting from a side slot 18 in the lounge base 12. The carriage assembly (not shown) supports and allows movement of the backrest 13 to allow a user to use the handle 17 to manually slide the backrest 13 along the seating surface 14. A hinged door 20 that leads to a storage area in the seat base 12 is also shown. As shown in FIGS. 1-6, the lounge assembly 11 is cushioned at the seating surface 14 and at the backrest 13. These cushioned areas are not shown in FIGS. 7-15 to facilitate illustration and understanding of operation of the lounge assembly.

By way of further explanation, FIG. 2 shows the lounge assembly of FIG. 1 from the other side, which has no handle 17 or door 20. FIGS. 3 and 4 show the lounge assembly backrest of the FIG. 1 embodiment in aftmost positions in upright and reclined position, respectively. FIGS. 5 and 6 show the same backrest in forwardmost position in upright and reclined position, respectively.

FIG. 7 is a side view of a lounge assembly 11 according to an embodiment of the invention having a backrest support 13 attached to the plate supports 15 (only one shown). The plate supports 15 project into the seat's base 12 through seat surface slots 21 to be carried on a carriage assembly 19. Cushioning for the backrest and the seating surface is not shown. A handle 17 connected to the carriage assembly 19 is also shown, as is the door 20 leading to a storage compartment.

FIG. 8 shows the carriage assembly 19 of an embodiment of the invention, to which the plate supports 15 are connected at each side thereof. The carriage assembly 19 is positioned beneath the lounge assembly seating surface 14 (FIGS. 1-6).

FIGS. 9 and 12 show in greater detail the carriage assembly 19 of FIG. 8 supported on wheels 21 which roll on a rail 23 within the lounge assembly 11. The rail 23 is shown in greater detail in FIGS. 10, 13, and 15 in engagement with wheels 21. The handle 17 is connected to a locking mechanism (FIG. 14) and can be used to cause the carriage assembly 19 to move by pulling on it, thus moving the backrest 13 into a desired position and then locking the backrest 13 in place. The handle locking mechanism includes a spring loaded lock 51 which engages a locking opening 31 for a desired backrest 13 position, as shown in FIG. 14.

FIG. 11 shows the backrest plate supports 15 (one shown) of an embodiment of the invention with detent mechanisms 41 and 43 which allow the backrest 13 to be moved between upright and reclined positions, and locked in place in the position desired.

Greater details about the locking mechanism of the handle 17 are shown in FIG. 14. The handle 17 is connected to the carriage assembly 19 and locks in place with a spring loaded lock 51. The locking mechanism of the handle assembly 17 can through spring loaded engagement have an end thereof enter one of several selected openings 31 in a panel in the slot 18 where the handle assembly 17 is located to lock the backrest 13 in a desired position.

While in one embodiment there are three locking positions, for example, with three openings for the locking mechanism of the handle assembly 17, it will be appreciated that the number of openings for the locking mechanism of the handle assembly 17 can vary depending on the number of locking positions desired for the backrest 13.

As previously noted, FIG. 15 shows the rail 23 in enlarged view. The rail 23 is engaged by carrier wheels 21 which are secured to carriage assembly 19 through thrust bearings 61.

FIG. 16 illustrates an alternate embodiment of a lounge assembly where a handle is attached to a backrest and the backrest moves only between two positions, here illustrated as center and to one end only. In this embodiment it is contemplated that a carriage assembly with support plates similar to those in the prior described embodiment may be used to move the backrest. It is further contemplated that a motor may optionally be connected to the carriage assembly to allow for powered movement.

The foregoing details and embodiments are exemplary only. Other modifications that might be contemplated by those of ordinary skill in the art are within the scope of this invention, and are not limited by the examples illustrated herein.
